As some of you already know, I have a pair of 2014 Burton Ambush's. Today while at my local resort I was tightening up the drawstring (whatever you want to call it) that tightens the liner and SNAP. Like what the? I didn't yank the drawstring or over tighten it...just steady slow tightening until it was snug. These boots had only been used a total of 16 times prior and have been well taken care off. Anyone else experience such disappointment?
